Answer (score: 0.5); 6. A Select three non-metal elements Arrange the selected elements in order of increasing oxidizing properties. 5) Cl 1) K 2) S 3) Si 4) Cd Answer (score: 1):

The correct answer is 2) S, 3) Si, 5) Cl.Explanation: Oxidizing properties refer to the ability of an element to gain electrons and form a negative ion. In general, non-metals have stronger oxidizing properties than metals. Among the given options, sulfur (S), silicon (Si), and chlorine (Cl) are non-metals. Potassium (K) and cadmium (Cd) are metals, so they are not considered in this question.Among the non-metals, sulfur (S) has the weakest oxidizing properties, followed by silicon (Si), and then chlorine (Cl) has the strongest oxidizing properties. Therefore, the correct order of increasing oxidizing properties is 2) S, 3) Si, 5) Cl.
